TODO current status in lunar and mainline.
The following commits had to be backported to Jammy:
Usually backporting new features to existing kernels it's not a common practice.
But these backports were easy to pick. Some of the commits were already applied.
More information about backporting these commits is addressed inline.
1. Add New CPU Model Number for EMR in Core Kernel: 7beade0dd41d
Already applied to jammy. Picked up in v5.15.80 upstream stable release
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2003122
2. Linux kernel: add EMR support to uncore-frequency driver: 9c252ecf3036
Had to adjust the path to uncore-frequency.c
In ce2645c458b5c83b0872ea9e39d2c3293445353a commit, this was moved to uncore-frequency dir
3. PMU Update to Support New EMR CPU model Number:
3.1 5268a2842066c227e6ccd94bac562f1e1000244f already applied from 5.15.91 upstream https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2011467
3.2 5a8a05f165fb18d37526062419774d9088c2a9b9
Small adjustment needed because saphire, raptor changes were not there.
3.3 6795e558e9cc6123c24e2100a2ebe88e58a792bc already applied from 5.15.93 upstream
https://bugs.launchpad.net/bugs/2012665
3.4 69ced4160969025821f2999ff92163ed26568f1c already applied in 5.15.91
https://bugs.launchpad.net/bugs/2011467
4. Perf RAPL PMU support on EMR: 57512b57dcfaf63c52d8ad2fb35321328cde31b0
Manually solved small conflict due to missing 80275ca9e525c
where a fixed DRAM domain energy unit is introduced
5. linux kernel: add EMR support to the intel_idle driver: 74528edfbc664f9d2c927c4e5a44f1285598ed0f
clean cherry-pick
6. intel-speed-select tool support for EMR: 61f9fdcdcd01f9a996b6db4e7092fcdfe8414ad5
clean cherry-pick
7. Turbostat support on EMR: 93cac4150727dae0ee89f501dd75413b88eedec0
clean cherry-pick
8. intel-RAPL drivers to support new EMR CPU model number: 7adc6885259edd4ef5c9a7a62fd4270cf38fdbfb
clean cherry-pick
9. Provide accel-config for EMR : TODO userspace
- this is user-space code, not kernel code (accel-config seems the
package that we already have in lunar, sync'ed from Debian, not
sure if we need to provide additional changes applied or if we
need to backport the whole user-space package to jammy)
10. Enable in-field Array BIST for EMR
code is still in the process of being reviewed, we shouldn't apply/backport this for now
11. CXL 1.1 Compatibility ECN
Very big patch -- won't port it to jammy
12. Split Lock detection change for EMR: d7ce15e1d4162ab5e56dead10d4ae69a6b5c8ee8
TODO linux-next only
13. Add Emerald Rapids CPU model number ID for EDAC driver support: e4b2bc6616e21
clean cherry-pick
Testing:
Kernel was built on cbd. roxanan-jammy-63b23a4757ba-H6S4

- 727209376f499 x86/split_lock: Add sysctl to control the misery mode
- b041b525dab95 x86/split_lock: Make life miserable for split lockers
- 054ed6349c1bd Documentation/x86: Update split lock documentation
And manually solved a conflict due to missing:
- d3287fb0d3c8a x86/microcode/intel: Expose collect_cpu_info_early() for IFS
- 3f2adf00f52b5 x86/cpu: Use MSR_IA32_MISC_ENABLE constants
- ef79970d7ccdc x86/split-lock: Remove unused TIF_SLD bit
which are just small improvements and not critical.
TODO more explanation here
13. Add Emerald Rapids CPU model number ID for EDAC driver support: e4b2bc6616e21
clean cherry-pick
Testing:
Kernel was built on cbd. roxanan-jammy-cd5956c49599-A3Ur
Regression potential
Very very low, these are new features, nothing to regress here. |

SRU Justification
[Impact]
Usually backporting new features to existing kernels it's not a common practice.
But these commits were easy to pick. Some of the commits were already applied.
More information about backporting these commits is addressed inline.
[Commits]
1. Add New CPU Model Number for EMR in Core Kernel: 7beade0dd41d
Already applied to jammy. Picked up in v5.15.80 upstream stable release
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2003122
2. Linux kernel: add EMR support to uncore-frequency driver: 9c252ecf3036
Had to adjust the path to uncore-frequency.c
In ce2645c458b5c83b0872ea9e39d2c3293445353a commit, this was moved to uncore-frequency dir
3. PMU Update to Support New EMR CPU model Number:
3.1 5268a2842066c227e6ccd94bac562f1e1000244f already applied from 5.15.91 upstream https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2011467
3.2 5a8a05f165fb18d37526062419774d9088c2a9b9
Small adjustment needed because saphire, raptor changes were not there.
done in 528c9f1daf20d "perf/x86/cstate: Add SAPPHIRERAPIDS_X CPU support"
3.3 6795e558e9cc6123c24e2100a2ebe88e58a792bc already applied from 5.15.93 upstream
https://bugs.launchpad.net/bugs/2012665
3.4 69ced4160969025821f2999ff92163ed26568f1c already applied in 5.15.91
https://bugs.launchpad.net/bugs/2011467
4. Perf RAPL PMU support on EMR: 57512b57dcfaf63c52d8ad2fb35321328cde31b0
Manually solved small conflict due to missing 80275ca9e525c
where a fixed DRAM domain energy unit is introduced
TODO not sure if this one is correct.
5. linux kernel: add EMR support to the intel_idle driver: 74528edfbc664f9d2c927c4e5a44f1285598ed0f
clean cherry-pick
6. intel-speed-select tool support for EMR: 61f9fdcdcd01f9a996b6db4e7092fcdfe8414ad5
clean cherry-pick
7. Turbostat support on EMR: 93cac4150727dae0ee89f501dd75413b88eedec0
clean cherry-pick
8. intel-RAPL drivers to support new EMR CPU model number: 7adc6885259edd4ef5c9a7a62fd4270cf38fdbfb
clean cherry-pick
9. Provide accel-config for EMR : TODO userspace
- this is user-space code, not kernel code (accel-config seems the
package that we already have in lunar, sync'ed from Debian, not
sure if we need to provide additional changes applied or if we
need to backport the whole user-space package to jammy)
10. Enable in-field Array BIST for EMR
code is still in the process of being reviewed, we shouldn't apply/backport this for now
11. CXL 1.1 Compatibility ECN
Very big patch -- won't port it to jammy
12. Split Lock detection change for EMR:
d7ce15e1d4162ab5e56dead10d4ae69a6b5c8ee8 linux-next
Had to apply the following:
- 727209376f499 x86/split_lock: Add sysctl to control the misery mode
- b041b525dab95 x86/split_lock: Make life miserable for split lockers

SRU Justification
[Impact]
Intel has introduced support for their new Emerald Rapids CPU.
This support is a nice feature to have in Jammy because it is an LTS release and enabling extra hardware adds to its usability.
Usually backporting new features to existing kernels it's not a common practice.
But these commits were easy to backport. Most of them were clean cherry picks. Some of them were already picked up from upstream stable releases,
and some required manual intervention because Jammy did not have some commits applied but the actual changes were very minimal.
